Not yet. Its certainly something that I want to support. I want to avoid supporting all the formats so settling on a few clear options in the space is the goal. Right now its only STL since its super standard and doesn't force me to cover everything. I will likely move away from STL as things settle.
Feel free to add a ticket requesting your favorite and I can look into moving to that format in the future.
Exporting to OBJ would get you 90% of the way there. If you're not doing anything but generating a mesh, then OBJ -> whatever converters exist for pretty much every datatype.
OBJ is also the easiest to implement, too. Assuming whatever geometry library you're using is using _real_ geometry and not using any sort of weird volumetric rendering, etc. then it should be 'trivial' to export to OBJ.
